The best gas boilers for heating areas up to 200-300 sq. m.
As the heated space increases, the problem of saving gas fuel becomes more acute. To ensure low heating costs, when choosing a boiler you need to pay attention not only to power, but also to its efficiency. For some models from this rating (they work on the condensation principle) it exceeds 100%. Such data were obtained in accordance with domestic calculation standards, and according to the European methodology, their real efficiency is approximately 95%. Accordingly, in order to get an idea of the real efficiency of simple floor-standing gas boilers, the calculated efficiency value should be reduced by 12-15%.

Project documentation. Coordination with authorities
Gas heating is a source of increased danger, so in order to carry it out, you will need to develop a project and coordinate it with certain services. First, an application is written to the supervising gas supply authority. You will need to indicate your planned consumption. You can calculate it knowing the future heated area: it must be divided by 10 kW per square meter. m. The resulting figure will be approximate. For an accurate calculation, you need to know the heat loss, as well as the amount in the heating system. The boiler can heat 12 liters efficiently. For this, 1 kW will be spent. Recently, a region coefficient has been applied to these calculations, based on the average annual temperature and season length.
The period for consideration of the application in this instance may be a week. After this, technical specifications for the development of the project are issued. Next, you will need to correctly design the connection diagram, according to the data received.
You can't do this yourself. Project documentation is carried out by organizations licensed for this type of activity. After the project has been drawn up, you will need to collect an additional list of papers related directly to the equipment: conformity assessment, technical passport, certificate, instructions. The entire package of documents received is submitted to the gas supply organization for approval. The process, depending on the season and complexity of the object, can last from a week to three months. After receiving permission, you can begin installation. If a refusal is received, the reason will be stated in it. The project will require revision and re-approval.
Installation of units
Floor-standing gas boilers for heating a private home must be installed and connected by specialists licensed for this type of activity. Most often this is done by employees of a gas supply organization, but related to the service department. This same department will then be responsible for the maintenance of the unit.
You can do the heating wiring around the house and install the boiler yourself. But insertion and connection should only be carried out by a licensed specialist. This condition is mandatory. Otherwise, the connection will be considered illegal and dangerous to others. The technician does the installation based on the diagram and equipment certificate. The same goes for the chimney. It must undergo inspection and fire safety testing.
Installation of the system should be carried out at a temperature range from +5 to +35 degrees Celsius. In order to ensure the safe use of gas heating, the operating instructions must be followed. There are a number of general points worth noting:
- Before turning on the equipment for the first time, you need to check the tightness of the pipe supply. This can be done by smearing the joint with soapy water. If bubbles appear, turn off the gas supply, ventilate the room and eliminate the leak.
- Do not expose the device to mechanical stress. The body of gas equipment is not designed to withstand impacts.
- If you smell gas during operation, call emergency services. Do not try to fix the damage yourself.
Brand rating
Calculating the average ratings by adding 0.5 points per plus, we have the following rating:

Technical conditions for connection
A household floor-standing gas boiler can only be installed by an organization and its employee that has a license to carry out such activities. Under no circumstances should you do this yourself. To install the heating device, the following technical conditions must be provided:
- There must be free access to the device at any time.
- The size of the opening to the boiler room is at least 800 mm.
- The area of the boiler room is at least four square meters.
- The ceiling height is at least two and a half meters.
- Water supply to the premises is required.
- Walls and floors must be covered with non-flammable materials: tiles, plaster.
- Be sure to install a chimney of the required diameter.
- If the heating device will operate with an electrical connection, the outlet must be grounded.
- It is imperative to have an opening window that will serve in necessary situations as a light source and exhaust hood.
- The floor must be level.
- Availability of supply and exhaust ventilation.
Gas equipment must not be installed in rooms without ventilation, dorm rooms, as well as in bathrooms, corridors, basements, balconies and basements. The equipment should not be placed close to walls lined with flammable materials. As you can see, floor-standing gas heating boilers require fairly stringent conditions for their connection. But, having completed all the points, you don’t have to worry about the safety of using such equipment.
